Ultrafine particles
(powders): Research interests include: (1) preparation of ultrafine powders by hydrothermal and sol-gel methods, and (2) powder characterization of size, shape, composition and surface area by using different techniques.

Sol-Gel Chemistry:
Research interests include: (1) preparation of nanocomposite and single phase sol-gel bulk materials and thin films for structural and electronic applications; (2) structural investigation of sol-gels by TEM and NMR; and (3) preparation and characterization of nanocomposites of clays, gels and zeolites for use as desiccants.
